smart csv perl library

Hi,
I am a data analyst.
I am reading a csv file. Each column in the csv file has a mapping to data based on the column name. e.g.
if csv file is something like:
key, column_b,column_c,column_d,..

then there is a mapping from column_a to a meaningful name coming from another file:
column_a,meaningful_column_a
same for column_b, etc..

I need a CSVReader that can be initialized with the mapping files and then be asked to read the csv file, the translation should happen behind the scenes and it should return me mapped column fields.

e.g. usage.


Code
my $csvReader =  new CSVReader(); 
$csvReader->initializeMappings(@mapping_files);
$csvReader->read($csv_file);
while($csvReader->hasNext()) {
my @columns = $csvReader->readNext();
}


Is there a library out there that does this smartly and can also take in configuration file specifying how to map column names. If it has other cool features that would be cool too.

thanks!

Matt
